Further Evidence against the Possibility of Faster-than-Light Particles

Abstract

Arguments are added to the growing number of arguments against the possibility of faster-than-light particles. Causal loops with faster-than-light particles are discussed in the framework of non-quantum special relativity. Thought experiments with steady currents of faster-than-light particles show that the reinterpretation principle is incompatible with the causality principle. If both principles are used consequently paradoxial situations arise. These are visualized utilizing Brehme diagrams. The final conclusion is that particles cannot travel on a macroscopic scale faster than light if space and time are homogeneous and if the relativity and causality principles are valid.
